They would need to specifically design it to handle more than 20W to handle more than 20W. The port has nothing to do with it, it all depends on what voltages and current the charging circuitry microchips can send to the battery.

To use usb-c like the ipads, they would need to use the same chips, which can handle more than 20w, no? They're just going to create a new, worse one for more money?

I’m no expert in what exact chips they use inside the iPads, but the charging circuitry of iPads is designed for much larger batteries and therefore would probably need much more unnecessary space, so they would probably need to design a new one.

If they could just use the same chips as iPads, they could’ve done this with Lightning too, given that the 2017 iPad Pro could already charge at 30W.

latest iphones actually do 30w too (13 pro max and 14 pro max)

No, the charging circuitry for USB-C isn't designed specifically for higher capacity batteries, that doesn't make any sense. My android phone can charge with usb-c at 65w, more than any iPad. Battery management is typically done with a battery bms attached to your iPhone's battery cell(s). There is no excuse.

You still emphasise my own point: It has nothing to do with USB-C. They could do 65W charging over Lightning. And they could do 20W charging via USB-C if they don’t change the charging circuitry from the current one. That’s all I’m saying.

65w charging over lightning, probably not tbh... may need a cable revision for that one
